XTC Japan Brain Hacker DX Male Masturbator

The XTC Japan Brain Hacker DX is a brain-shaped male masturbator with a 7.1-inch tunnel and seven textured zones. Its sculpted folds give under gentle pressure, so you can vary your grip on the soft TPE body.

Inside the masturbation sleeve, rounded bumps and narrower passages change the feel along one continuous channel. At 5.5 inches wide and 1.2 kg, this substantial male stroker has room for a two-handed grip to support its weight.

How to Use and Clean

Wash the sleeve before first use. Apply water-based lubricant to the opening and inside the tunnel.
Support the body in your hands and start with a light grip. Choose a comfortable depth and pace. Adjust your grip to vary the pressure. Add more lubricant if you feel friction.
After use, wash the outer folds and the tunnel with lukewarm water and a sex toy cleaner suitable for TPE. Rinse thoroughly, including inside the textured sections.
Let the water drain through the opening and allow the tunnel to dry fully before storing.

Brain Hacker DX FAQs

Can I explore the texture without using the full 7.1-inch depth?

Yes. The seven zones run along one continuous tunnel. Shorter movements let you explore the textures nearer the entrance and choose a depth that feels comfortable.

What does the 5.5-inch width measure?

It measures the outside of the toy from side to side. Use that figure to judge how it will sit in your hands. The measurement for internal depth is the 7.1-inch tunnel length.
